The classic British-Made portable and bench-top Geiger Counter, justly famed for its large and easy to read meter, rugged construction and simple controls.

Popular in industry, education, schools, colleges and with experimenters, collectors and hobbyists. It’s tough and reliable with useful features like a built-in speaker, user settable alarm and detachable probe.

This is sensitive to beta and gamma radiation in the range 30keV to 1.25MeV and can be powered by 6 AA calls or an external 12-18 volt DC supply. This unit has been pre-owned but it is in full working order and virtually as-new condition.
